Explanation:
Portuguese navigator
Fernando
de Magellan and his crew had plenty
of time to study the southern sky during the
first circumnavigation of planet Earth.
As a result, two fuzzy cloud-like
objects easily visible for southern hemisphere skygazers
are known as the
Clouds of Magellan.
Of course, these star clouds are now understood to be dwarf
irregular galaxies,
satellites of our larger spiral
Milky Way galaxy.
The Large
Magellanic Cloud (LMC)
pictured above is only about 180,000 light-years distant in
the constellation
Dorado.
Spanning about 15,000 light-years or so, it is
the most massive of the Milky Way's satellite galaxies
and is the site of the
closest
supernova in modern times.
The prominent red knot on the right is 30 Doradus, or the
Tarantula Nebula, a giant star-forming
region in the
Large Magellanic Cloud.
